At first look it may seem as a good inplemented game. However, it have several problems
-- Main problem is monotony and boredom. There is only 4 types of enemies encountered through campaing, including 0 bosses. You do exactly same thing over and over - try to dodge (if you hit, its OK - you have a lot of HP), shoot at them, bomb if huge wave of small vessels appears, shield if fighters from side of screen fly or you have no bombs. Repeat over all 10 levels, which are only differ in amount of enemies to shoot.
-- Even one thing game have to offer is not good. Of 4 weapons, only first one is useful, since its deals most DPS and all enemies are destroyed faster (tested multiple times). Shields are OP. Upgrades are earned TOO easily - max all stats by level 8-9 or earlier if you are good at collecting - and thats not counting grinding...
-- Excuse plot. Terrible excuse plot!
-- Special dislike and - 0.5 star for flamethrower IN SPACE. Don't even bother to try to explain this...
+ Graphics are relative good. But nothing special.
Thats it. Project that could be good is actually low-level crap.
